Dear OTB community,

We are happy to announce that OTB version 9.1.0-rc2 has been released! Compare to version 9.1.0-rc1 this version corrects a bug in Spot5 orthorectification.

Ready to use binary packages are available on the package page of the website:

The Docker image are available with different python version (3.8 by default, 3.10 for 9.1.0-rc2_ubuntu22, 3.12 for 9.1.0-rc2_ubuntu24) :

docker pull orfeotoolbox/otb:9.1.0-rc2

It is also possible to checkout the branch with git:

git clone https://gitlab.orfeo-toolbox.org/orfeotoolbox/otb.git OTB -b release-9.1

The documentation for OTB 9.1.0 can be found here.

This release introduces bug fixes, important dependencies update (jpeg turbo, geotiff and GDAL), documentation improvement and the support of SPOT5 (previously drop in OTB8 as OSSIM dependency was removed).

Since version 9.0, the whole new packaging system is entirely made with CMake / CPack, to make the toolbox more modular. You still have the possibility to have a full package for Linux and Windows, but for those who want to install only a part of the toolbox it is possible since v9. The modules list is available in the cookbook with their associated applications. All the packages are now in tar.gz and the installation is movable unlike OTB < 9.

Reminder: Since release 9.0, all GUI has been dropped. QGIS is now the official visualization tool. We support the development of a plugin which you can use with the following instructions. Thus like 9.0 the version 9.1 does not include Monteverdi or Mapla.

Like version 9.0, Mac version is not supported, you can use docker image.

To download the packages one by one for a modular installation, you can download them here and follow the instructions in the cookbook.

The full changelog can be accessed here. We welcome your feedback and requests on OTB’s GitLab and if you find a bug, please report it!
